This invention relates to-portableul folding:

chairs adapted to' be .readily secured to a chair board or otherhorizontal member, and capable of being. quickly collapsed into a structure adapted to be conveniently carried. l

Itis the main object `of the invention to provide asimple but highly efficient folding chair of this nature, which may be readily set up for use or collapsed to be carried,

equipped with a comfortableseat section and back rest..

A' further object vof the invention is to provide in sucha device aI folding resilient back adapted, when set 'up for use, to conform to the contour of the user and still be capable of being folded down substantially fiat with theseat section of the chair.

It is a more specific object to construct the 'entire framework and back of the device from twisted resilient wire and vnevertheless provide a constructionwhich will be strong, durable and comfortable, though light in weight and occupying httle space.

A still further object ofthe invention is to provide a portable folding chair having means integral with the rame thereof whereby the seat portion may be readil atl. tached to the seat boar'd of arow oat, to grandstand or ordinary at bench. The 1nvention is thus especially adapted for use by Sportsmen and campers or footballV and baseball' fans, where comfort, 'as well as the preservation of the clothing worn, is desired. These and other objects 'of the lnvention 'will be apparent from the following description made in ,connection with the accompanyingV drawings wherein llke characters refer to similar arts throughout the several Fig. 1 is a vertical cross section taken through a rowboat with'the preferred form of the invention mounted therein upon the.

Fig. 6 is a detailed view on an enlarged scale vshowing the means for pivoting the l'ba"clz`section vvto the seat-section.

flat bottomed rowboat is indi- In Fig. 1 a cated by the numeral 7 having'the usual transverse seat board 8-supported by the cleats 9." *They referred form of the inventionv illustrate wardly to `afford the resilient clips 11, said lclips equipped with .outwardly `extending similar shape to said frameis -secured thereto in .a suitable manner. Through eyes 13 progecting lugs or bolts y15 are passed and secured, the purpose of which will l'ater be explained.

A spring skeleton back-is provided comprising preferably a pair of substantially U-shaped members 16 constructed of resilient wire having their outer arms supplied with eyes 16 adapted to be engaged b pivot members 17 passed therethrough and through the eyes 12 on the sides of said frame to pivotally secure the back section to said frame. The U-shaped members 16 are secured together b a member 18 extending therebetween an twisted about the inner armsl thereof, forming, in cooperation with the extremities of said innerarms', notched portions 19 constituting a pair `of props adapted to engage the projecting lugs 15 when said back section is swung back to nor? mal operative position. Loops '20 are lpreferabl bent in the U-shaped member '16 to comprises .a substantially .'Ufsbaped frame 10 constructedv from bent resilient wire having lits outer ends bent inafor a greater amount of resistance surface for the person using said chair. Loops 20 and the-closed 'portions of U members 16 constitute back supporting means conform- -ing approximately to the back of a person utilizing the chair.

The back section, obviously, may be folded against the seat section, the resiliency of the sired.

vvire construction permitting the outer arms thereof to be extended below and about the loops ll to hold the device in compact collapsed position when so desired. The eyes 11' may also be used for positively securing the frame l0 to a horizontal member if de- The folding seat may obviously be quickly installed on a seat board oi a rowboat or a randstand by slipping the clipsv l1 about t e outer edges thereof and swinging the back section outwardly, simultaneously sprin ing the bracing members or props sligliybackwardly and engaging the notched portions 19 thereof with the proecting lugs 15. When in such position, the 'ack Section of the seat will take a substantially horizontally curved position, thereby conforming to the contour of the back of a person using said seat. l

It will be obvious that sufficient resiliency will be embodied in the back section to afford a spring back for the user, supplying couiort as well as strength in the device.

From the foregoing description, it will be apparent that a useful and comfortable folding seat has been invented, capable of Wide general use and adapted to be collapsed in a compact structure occupying little space.

The use of this device will prevent the soiling of clothes aswell as provide a comtortable seat and back rest for a sportsman, camper, or football and baseball ian.

It will, of course, be understood that variu ous changes may be made in the form, de-

tails, proportions and arrangement of parte Without departing from the scope of the inyention.

What is claimed is:

l. A folding chair having in combination a seat section andl a spring skeleton back section, said back section comprising a pair ofV substantially U-shaped resilient wires havin their outer legs pivoted intermediate the si es ofsaid seat section, means for connecting the inner legs of said U-'shaped wires together and means at the rear of said seat section for engaging the inner legs of said U-shaped Wires, whereby said back section may be either collapsed flat against said seat section or raised to upward position and the inner-'legs of said U-shaped Wires may be' sprungzback behind said seat section and secured by said en aging means.

2. A folding c air having in combination,

-neath said lugs to lock said back section in collapsed condition against said seat sec tion.
